Method and apparatus for deploying computer networks

ABSTRACT

A method for deploying computer networks in a network environment is disclosed. Initially, a broadcast message is transmitted by a network device within a server to a network in order to investigate the availability of the network. A determination is made as to whether or not a response message responding to the broadcast message has been received by the network device within the server. If a response message has been received by the network device, it means the network is available and the network device can be configured to connect with the network. However, if no response message has been received by the network device, it means the network is not available and the network device can be configured as a server node of the network.

PRIORITY CLAIM

The present application claims benefit of priority under 35 U.S.C. §§ 120, 365 to the previously filed Chinese Patent Application No. 201510897654.3 with a priority date of Dec. 8, 2015, which is incorporated by reference herein.

TECHNICAL FIELD

The present invention relates to computer networks in general, and in particular to a method and apparatus for automatically configuring new servers in a data center to deploy computer networks within a network environment.

BACKGROUND

A network environment may include one or more computer networks, and each computer network may have multiple servers. Servers from different manufacturers may have different hardware from each other as well as different operating systems installed. In addition, each server within the computer network typically has multiple network cards. Thus, it is quite difficult to automate the initial build process of a computer network because many processes cannot be automatically performed at an infrastructure implementation stage.

Currently, many steps of the computer network deployment method have to be done manually in order to ensure correct configurations of the computer network. Needless to say, performing, network deployment steps manually is the most time-consuming part of the network deployment process and it is very prone to errors.

Consequently, it would be desirable to provide an improved method for deploying multiple computer networks within a network environment.

SUMMARY

In accordance with one embodiment of the present disclosure, a broadcast message is transmitted by a network device within a server to a network in order to investigate the availability of the network. A determination is made as to whether or not a response message responding to the broadcast message has been received by the network device within the server. If a response message has been received by the network device, it means the network is available, and the network device can be configured to connect with the network. However, if no response message has been received by the network device, it means the network is not available, and the network device can be configured as a server node of the network.

All features and advantages of the present disclosure will become apparent in the following detailed written description.

DETAILED DESCRIPTION

Referring now to the drawings and in particular to FIG. 1, there is depicted a block diagram of a group of new servers that can be automatically configured to deploy computer networks within a network environment. As shown, within a network environment 200, there can be one or more computer networks, such as network 1, network 2 and network 3. New servers 100 a-100 n located in a data center, for example, can be automatically configured to deploy networks within network environment 200. Although each of servers 100 a-100 n may have different hardware and software installed, the following is a description of server 100 a, as an example, in which the method of the present disclosure can be incorporated.

With reference now to FIG. 2, there is depicted is a block diagram of a server that can be configured to deploy a computer network, in accordance with one embodiment of the present disclosure. As shown, server 100 a includes a processor 110, memories 120, network cards 130 and a network deployment module 140. Processor 110 can be coupled to memories 120, network cards 130 and network deployment module 140 via a bus 150 and/or other forms of connecting mechanisms (not shown).

Processor 110 can be a central processing unit (CPU) or other forms of processing unit with data processing capability and/or instruction execution capability, which is configured to control various components within server 100 a to perform the desired functions accordingly.

Memories 120 include various forms of computer-readable storage media, such as a volatile memory 121 and a non-volatile memory 122, for storing one or more computer program products. Volatile memory 121 may include, for example, a random access memory (RAM), a cache memory and the like. Non-volatile memory 122 may include, for example, a read-only memory (ROM), a hard disk, a flash memory and the like. One or more computer program instructions can be stored within memories 120, and processor 110 can execute the program instructions to achieve the function of the method of the present disclosure and any other desired functions.

Network cards 130 can be utilized by server 100 a to communicate with other servers within the same network or other networks. Network deployment module 140 performs the necessary functions to deploy a computer network.

It should be noted that the components and structures of server 100 a in FIG. 1 are illustrative only and not restrictive, and server 100 a may include other components and structures as needed.

Referring now to FIG. 3, there is depicted a detailed block diagram of network deployment module 140 from FIG. 1, in accordance with one embodiment of the present disclosure. As shown, network deployment module 140 includes a transmission unit 310, a determination unit 320 and an establishment unit 330. Transmission unit 210 may communicate with various network cards within other servers of the same computer network and other computer networks by, for example, obtaining or leasing a temporary IP address in order to transmit a broadcast message (such as a ping message) to each of the various network cards within other servers.

Transmission unit 310 may compile the corresponding IP addresses of all the network cards within all the servers. The order of transmitting broadcast messages from transmission unit 310 can be predetermined and prioritized. For example, higher status network(s) within the network environment will be given priority accordingly.

Transmission unit 310 can sequentially transmit broadcast messages to the various network cards in order to detect the status of the corresponding computer network within the network environment, and to determine whether or not server 100 a can serve as a server node for connecting with one or more other computer networks within the network environment such that a computer network can be deployed automatically and reliably. Determination unit 320 determines whether or not a response message responsive to a broadcast message has been received. If no response message corresponding to a particular broadcast message has been received, establishment unit 230 will then provide a server node to connect the sending server into the one or more computer networks of the network environment. Establishment unit 330 may be implemented as a Dynamic Host Configuration Protocol (DHCP) server, for example. Optionally, establishment unit 330 may include a sequence acquisition unit to acquire a preset sequence of communicating sequentially with corresponding network cards of other servers within the computer network.

With reference now to FIG. 4, there is depicted high-level flow diagram of a method for configuring a server to deploy a computer network, in accordance with one embodiment of the present disclosure, Staring at block 400, a network device, such as network card 130 from FIG. 2, within a new server, such as server 100 a from FIG. 2, is configured to detect the status of a computer network within a network environment by sending a broadcast message to another server within the computer network, as shown in block 410.

Next, the server determines whether or not a response message responsive to the broadcast message has been received from the computer network, as depicted in block 420. If a response message has been received from the computer network, the server can conclude that the computer network is available, and the network device can be configured device to connect with that computer network, as shown in block 430. For example, an IP address of the network device can be configured based on the received response message.

However, if no response message has been received from the computer network, the server can conclude that the computer network is not available, and the network device can be configured as a server node of that computer network, as depicted so in block 440. For example, the network device can be configured as a server node of the network by initiating a client-server protocol, such as a Dynamic Host Configuration Protocol (DHCP).

Using new servers 100 a, 100 b and 100 c in FIG. 1 as an example, and if each of servers 100 a-100 c includes network cards Ax, Ay and Az, and the network environment includes network 1, network 2 and network 3, then the following steps will be performed to check the status of various computer networks:

-   -   (1) Network card Ax sends a broadcast message to network 1. If         no response is received, then go to (2). If a response is         received, then obtain network card Ax's IP address, and go to         (4).     -   (2) Network card Ax sends a broadcast message to network 2. If         no response is received, then go to (3). If a response is         received, then obtain network card Ax's IP address, and go to         (4).     -   (3) Network card Ax sends a broadcast message to network 3. If         no response is received, then go to (4). If a response is         received, then obtain network card Ax's IP address, and go to         (4).     -   (4) Network card Ay sends a broadcast message to network 1. If         no response is received, then go to (5). If a response is         received, then obtain network card Ay's IP address, and go to         (7).     -   (5) Network card Ay sends a broadcast message to network 2. If         no response is received, then go to (6). If a response is         received, then obtain network card Ay's IP address, and go to         (7).     -   (6) Network Ay sends a broadcast message to network 3. If no         response is received, then go to (7). If a response is received,         then obtain network card Ay's IP address, and go to (7).     -   (7) Network card Az sends a broadcast message to network 1. If         no response is received, then go to (8). If a response is         received, then obtain network card Az's IP address, and go to         (10);     -   (8) Network card Az sends a broadcast message to network 2. If         no response is received, then go to (9). If a response is         received, then obtain network card Az's IP address, and go to         (10);     -   (9) Network card Az sends a broadcast message to network 3. If         no response is received, then go to (10). If a response is         received, then obtain network card Az's IP address, and go to         (10);     -   (10) If no network, then set IP address of network card(s)         according to network design.     -   (11) Clear network table; server configuration is completed.         Each of servers 100 b and Me then performs the above-mentioned         steps (1)-(11) to complete the server configuration process.

The server communicates with each of the network cards within each of the is other servers in a sequential manner by, for example, obtaining or leasing a temporary IP address in order to transmit a broadcast message to each of the network cards. The order of receiving broadcast messages by the servers may be predetermined and prioritized. For example, the higher priority computer networks will be receiving broadcast messages before the lower priority computer networks.

As has been described, the present disclosure provides a method and apparatus for configuring servers to deploy computer networks in a network environment. By configuring a server to deploy a computer network, network deployment can be achieved automatically without being constrained by various conditions such as the number of networks, the number of network cards, the type of operating systems, the layout of the physical servers, etc. As a result, the efficiency of the process of deploying computer networks is greatly enhanced, which is particularly advantageous in the scenario of batch deployment of large platforms.
